Frequently Asked Questions


Credosity is secure — your writing isn’t shared with or viewed by anyone (computer or human). Our clients are enterprises. Almost everything they write is considered sensitive or confidential.

The statistics we capture are based on your performance only (e.g. number of documents/emails you’ve reviewed, how often you use Credosity), and never record or capture the actual content of your document or email.
